We've done outside breedings here but this is MY first mare (she's 6 yr old). Two of the mares brought here had the regumate cycling and one didn't take so she had to come back. The other had the Regumate AND the shot and she was SOOO ready that my gelding was hanging out and dripping. Another mare, 5 yr old madien, came when the owner "thought" she was cycling and BANG she was!
So when it comes to my own mare I'm totally in the dark. As I said she has silent heats. She is not one to get moody. She's a down to business - do her job sort of gal. Out of 3 vets, when asked about breeding, 0 did anything but do a superfical look. I asked if she should have blood tests - NO. I asked if she looked big enough to carry and give birth (she's 34") and none wanted to examine her. The last one only said, "Here, give her Regumate for 10 days and wait 5 more days."
Well, I'm still waiting --it's day 6. Trouble is I'm not sure what I'm waiting for as neither are giving me any signs. And yes he did show an interest last summer (around July or Aug--yuck!) and she was so/so about his sniffing around. No I didn't let them breed that late in the summer. I'm just frustrated, I guess.
